Answer:
27
Step-by-step explanation:
Let :
Number of 40¢ = x
Number of 22¢ = 4x + 3
Total stamp value = $8.34 = (8.34 * 100) = 834¢
40¢x + 22¢(4x + 3) = 834¢
40x + 88x + 66 = 834
128x = 834 - 66
128x = 768
x = 768 / 128
x = 6
Number of 22¢ stamp:
4(6) + 3 = 24 + 3 = 27
Answer: You can’t get an exact number cus you can’t subtract p from p, but I did get
(p-4) (p+3)
meaning you multiply (p-4) by (p+3)
Step-by-step explanation:
Product is the answer to a multiplication problem
Sum is the answer to an addition problem
p squared - p - 12 =
(p-4)(p+3)
Answer:
There is not enough info to solve this. And if 4/3 is the base you do
(4/3)(4/3) which equals 16/9 = 1 7/9
From sin(a-b) = sin(a)cos(b) - cos(a)sin(b)
let a=9x, b=x
sin(9x)cos(x) - cos(9x)sin(x) = sin(9x-x) = sin(8x)
Answer:
5305.1647 times
Step-by-step explanation:
The Circumference of a circle : πd
d = diameter of circle = 30 cm
Circumference of wheel = π * 30cm = 94.247779 cm
1km to cm
1km = 100000cm
5 km = 500000 cm
Hence, number of times wheel rotate on a 5km journey :
500000 cm / 94.247779 cm
= 5305.1647 times
